Title: Catalysts for the production of cast polyamide, processes for production thereof and use thereof
Inventor: LAUFER WILHELM
IPC: C08G69/20
Filed: 2013-06-06
Granted: 2020-01-14
Abstract: The present invention relates to novel catalysts for the production of cast polyamide, to processes for production thereof and to the use thereof. The novel catalysts comprise a) lactamate, b) at least one of alkali metal salt of aminocapronates or aminolaurates, and c) a lactam such that the ratio between constituents a) and b) is between 3:1 to 50:1 and the proportion of lactam based on constituents a) and b) is less than or equal to 99% by weight. This composition avoids the excessively high and non-constant reactivity in cast polyamides seen with the current catalysts.

Granted: 2021-05-25
Abstract: L'invention concerne un système de mélange de boue liquide qui calcule une densité d'une boue liquide en utilisant un différentiel de pression mesuré et une vitesse de propagation de la boue liquide. La boue liquide produite par le mélange sec et le fluide de mélange pénètre dans une ou plusieurs cuves contenant des agitateurs. Une pompe pompe alors la boue liquide hors de la ou des cuves vers le puits et une portion de la boue liquide est remise en circulation vers une mélangeuse. Depuis le trajet de remise en circulation, un détecteur direct de poids de boue liquide mesure un différentiel de pression de la boue liquide entre deux points de mesure verticaux d'un volume connu et le détecteur mesure une vitesse de la boue liquide remise en circulation. En se basant sur ces mesures, le contrôleur calcule une densité de la boue liquide, surveille un rapport entre le mélange sec et le fluide de mélange et ajuste le rapport en se basant sur la densité calculée de la boue liquide s'il existe une divergence.

Granted: 2023-02-28
Abstract: A multi-phase separation apparatus is provided that shapes the flow in a flow shaping line having a plurality of loops with consecutively decreasing diameter. Centrifugal force drives the heavier, denser liquid of a two-phase flow to the outside wall of the flow shaping line and allows the lighter, less dense vapor or gas to occupy the inner wall of the flow shaping line. With the gas positioned on the inner wall of the flow shaping line, an exit port on the inner wall will allow the majority of the gas, along with a low amount of liquid, to be sent to a conventional separator. The remaining liquid is subsequently introduced into an adjustable phase splitter to separate different liquid components from one another.
